+## The links in the navigation sidebar can be configured.
+## To add a link to the sidebar, add a line like the following
+#
+# $wgNavigationLinks[] = array( 'text' => 'helpdesk', 'href' => 'helpdesk-url' );
+#
+## and create two MediaWiki:-pages with the corresponding names, e.g.
+## MediaWiki:helpdesk="User help desk"
+## MediaWiki:helpdesk-url="YourProject:Help_desk"
